Sending, receiving, and organizing email in Outlook.com
Hi, I'm John! I will help you with this.
To help narrow down the issue:
- What type of emails are missing? For example, bank alerts, newsletters, business emails, or emails from a specific person?
- Have you checked the Deleted Items, Archive, and Other/Focused Inbox folders?
- If you sign in through Outlook web https://outlook.live.com/mail do the missing emails appear there?
